UNITED STATES WEATHER STRIPPING Louis A. Macklanburg, Oklahoma City, Okla. Application July 27, 1931. Serial No. 553,394

' aciaims. (01. 20-69) v of being applied towindows, doors and theirv frames without nails or tools.

The invention consists in the novel construction, arrangement and combination of parts in a Weatherstrip and certain improved construction in coacting grooves in window, door and frame members as hereinafter more particularly described and claimed.

Inthe drawings:

Figure 1 is a vertical transverse cross section (parts omitted) through a double sash window frame and windows, showing the improved weather stripping applied both to the sash rail members in the middle, the frame at the top, and the sill at the bottom;

Figure 2 is a fragmentary horizontal cross section showing the improved weather stripping applied to the side jamb;

Figure 3 is an enlarged cross section similar to the showing in Figure 2; a

Figure 4 is a fragmentary. perspective of the improved strip showing one type of groove engaging member;

Figures 5, 6, and 7 are cross sections similar to Figure 3, showing modified forms of groove engaging members. v

In accordance with the present invention, the improved Weatherstrip is formed from an elongated strip of resilient spring metal bent on longitudinal lines to form a medial longitudinally extending seat part 1, to one side of which is positioned a longitudinally extending groove engaging part 2. On the other side of the medial seat part 1 is positioned a slide ridge part 4 and intermediate said seat 1 and slide ridge part 4 is a resilient spring part 3 disposed at an angle with respect to the said seat part 1.

The edge part of the strip adjacent the ridge slide part 4, indicated at 5, is preferably arranged in a plane parallel with that of the seat part 1 and constitutes a stop slide for the ridge slide member 4.

The groove engaging member 2 may be formed in a variety of ways all of which, however, involve the bending of a part of the strip adjacent said part 1 substantially perpendicular to said seat part and then bending the outer edge part of the strip downwardly at an angle thereto, thus forming an enlarged marginal part. This enlarged marginal part may be of general V-shape in cross section, as illustrated inFigures 3, 4, 5 and 6, or a U-shape, as'illustrated in Figure 7, with the free leg of the U bent strip.

inwardly. The free edge part of the groove engaging member may be slotted transversely of the strip, as illustrated in Figure 4, and the'partsj intermediate the slots, as at 8, are formed in sawtooth manner to provide resilient wood engaging 'prongsada'pted to automatically prevent withdrawal of the strip from a groove after same has been forced therein. i

Alternatively wedge-shaped members 11, .as

illustrated in Figure 6 or 11' as illustrated in Figure 5, may be used to expand the groove'engaging part within the groove in the sash or frame member and to interlock the same in said groove.

In applying the groove, itis desirable to provide undercut grooves in the rails R,- jam J and sill S, which undercut groovesmay be formed as I illustrated in Figures 3,5 and 6, with inwardly with downwardlyjfacing inclined shoulders 7., adapted to co-act with the groove engaging member of the strip to vsecurelyint'erlock the stripfacing shoulders 7, or as illustratedin Figure 'l,

with the groove and to eliminate all use of 7 screws, nails, or the like in applying the weather a The adjacent parts of the sashes are grooved as at 12 and 12' to receive the'slide ridge of the weather strip.

It will be noted that with the weather strip construction described, it can be readily and quite efficiently applied to frames and sash at the will and that in operation the association of the slide ridge of the Weatherstrip with the adjacent grooved parts of the sash affords-a most efiicient wind-break as any windpressure through the parts will tend to more effectively seatthe The application and operation of the improved strip will, be obviousto those skilled in the art.
